• Answer:-

    Alveoli are tiny, balloon-like air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. They're crucial for breathing because they provide a large surface area for gases to diffuse between the air and the bloodstream. When you inhale, oxygen passes through the thin walls of the alveoli into the blood, and when you exhale, carbon dioxide from the blood is released into the alveoli to be breathed out. This efficient gas exchange is vital for maintaining the oxygen levels your body needs to function properly.
